Mr. [Steve] Jobs (co-founder of the company) has been the most prominent salesman of the personal computer revolution, preaching that the new technology would change everyone's lives. And just as Mr. Jobs is falling, the revolution he foretold is stalling: Consumers and businesses are slowing their purchases of computers and questioning how much they really need the machines. (ha!)

Mr. Jobs's resignation, which followed a long corporate power struggle, also exemplifies a situation common to the entrepreneur: an inability to adjust as the company grows larger and the nature of the business changes.
